PATENT GEORGE OHAMBERLIN AND \VILLIAM H. GHAMBERLIN, OF OLEAN, N. Y.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 301,564, dated July 8,1884.

Application filed March 19, 1884. (No model.)

To all whom it may concern-.-

Be it known that we, GEORGE CHAMBER- LIN and WILLIAM H. GHAMBERLIN,citizens of the United States, residing at Olean, in the county ofCattaraugus and State of New York, have invented certain new and usefulImprovements in Bottle-Stoppers; and we do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part, ofthis specification.

Figure 1 is a central vertical section of the bottle-stopper in abottle, shown as closed therein. Fig. 2 is a similar view with thestopper opened; Fig. 3 a side view of the stopper proper; Fig. 4, a viewof the bottle packing-tube detailed.

Like letters designate corresponding in all of the figures.

Our invention belongs to the class of removable inside stoppers; and itconsists in the combination, with a bottle provided with a freelyremovable packing-tube on the inside of the neck of a stopper, of a diskform, and provided with a stem adapted to keep the stopper in positionin the neck of the bottle, substantially as hereinafter specified.

The construction is substantially as follows The stopper proper consistsof a disk, A,

parts preferably convex or broadly conical on the outer side, and of adiameter a-little less than that of the neck a of the bottle. A stem, B,consisting of a wire extended outward through and beyond the neck of thebottle, and bent at 22 once or twice in a circle or approximate shape toform a loop or eye for drawing it into the neck of the bottle, andthence extended inward nearly to the disk again, and left free to yieldinward and spring outward. This stem thus constructed not only serves tomanipulate the stopper with, but the additional purposeof holding thestopperdisk at right angles to the axis of the bottle-neck, which isnecessary for performing its proper function.

This stopper is used in connection with a packing-tube, O, of softindie-rubber or equivalent material, which is inserted in the neck ofthe bottle, preferably far enough to reach a little into the innerflaring part of the bottle-neck. When the stopper is placed in a bottleand the packing-tube also inserted in able and efficient.

the neck of the bottle, then, by drawing on the stopper-stem, the disk Ais drawn into the inner end of the packing-tube O-until the diminishinginterior diameter of the bottle-neck prevents it being drawn any fartheroutward, when it will completely and effectually stop the bottle, asshown in Fig. 1. Then, on driving in the stem B by any means, thestopper assumes the position shown in Fig. 2, ready for pouring out theliquid in the bottle. The sides of the stem B of the stopper, pressinginto the interior surface of the packing-tube 0, hold the stopper open.Vhile the stopper is in this latter position the packingtube can bereadily pulled from the neck of the bottle by pliers or other suitablemeans, and then the stopper itself is readily drawn out, leaving thebottle free to be washed or cleaned out.

Packing tubes, in connection with inside stoppers, have been usedbefore, when they form a part of the stopper itself, and are insertedand withdrawn therewith. This requires a more or less complexconstruction and at considerable cost, whereas our sepa ratepacking-tube, inserted in and forming an ordinarily inseparable partthereof, allows the utmost simplicity of the stopper itself, very cheapand easily manipulated, as well as durvVe are not aware that thisconstruction has been known before. A1so,botties with interior ring ortube-packing and inside stoppers of conical or spherical form havebefore been used; but the extended surface of contact between thepacking and stopper cannot always be relied on to produce anair-tightjoint necessaryfor this purpose; but with a thinedged disk. like ourstopper pressing against the packing, the joint on the side of thepacking is always reliable. \Ve claim as our invcntion- The combination,with a bottle provided with a freely-ren1ovable packing-tube, G, on theinside of its neck, of a stopper, A, of disk form, and provided with astem, B, adapted to keep the stopper in position in the neck of thebottle, substantially as and for the purpose herein specified.

In testimony whereof wc affix our signatures in presence of twowitnesses.
